Study Notes
Wave Basics
- Waves are a transfer of energy through a medium from one point to another.
- Examples include water waves, sound waves, and radio waves.
- Two main forms of waves:
- Transverse Waves: Move the medium perpendicular to wave motion (e.g., vibrating guitar string, electromagnetic waves).
- Longitudinal Waves: Move the medium parallel to wave motion (e.g., "Slinky" wave).
Wave Properties
- Crest: Maximum upward displacement in a Transverse wave.
- Trough: Maximum downward displacement.
- Amplitude: Measurement of maximum displacement from the rest position.
- Wavelength (λ): Distance of one complete wave cycle (measured crest to crest or trough to trough).
- Compressions: Areas of maximum displacement in Longitudinal waves.
- Rarefactions: Areas of minimum displacement in Longitudinal waves.
Wave Velocity Equation
- Equation: Velocity (v) = Wavelength (λ) x Frequency (f).
- Applicable for all wave forms including water, sound, and radio waves.
Example Calculation
- For a wave with a wavelength of 5 meters and a frequency of 10 Hz:
- V = 5 x 10 = 50 meters per second.
Velocity Calculation Problems
- Wave with a wavelength of 12 meters and frequency of 10 Hz:
- V = 12 x 10 = 120 m/s.
- Wave with a wavelength of 3 meters and frequency of 15 Hz:
- V = 3 x 15 = 45 m/s.
- Wave with a wavelength of 18 meters and frequency of 0.5 Hz:
- V = 18 x 0.5 = 9 m/s.
- Wave with a wavelength of 0.5 meters and frequency of 100 Hz:
- V = 0.5 x 100 = 50 m/s.
Summary of Wave Characteristics
- Longitudinal wave motion is parallel to wave direction.
- Wavelength is defined as one complete wave cycle.
- Maximum displacement in a Longitudinal wave can be compressions or rarefactions.
- An ocean wave is a classic example of a Transverse wave.
Measurement Units
- Wavelength is measured in meters (m).
- Frequency is measured in Hertz (Hz).
Important Definitions
- Crest: Highest point of a wave.
- Trough: Lowest point of a wave.
- Amplitude: Height from the rest position to crest or trough.
- Compression: Area of high pressure in Longitudinal waves.
- Rarefaction: Area of low pressure in Longitudinal waves.
